3 # This file lists the configuration options that are used when building the
4 # hostapd binary. All lines starting with # are ignored. Configuration option
5 # lines must be commented out complete, if they are not to be included, i.e.,
6 # just setting VARIABLE=n is not disabling that variable.
8 # This file is included in Makefile, so variables like CFLAGS and LIBS can also
9 # be modified from here. In most cass, these lines should use += in order not
10 # to override previous values of the variables.

224 # hostapd depends on strong random number generation being available from the
225 # operating system. os_get_random() function is used to fetch random data when
226 # needed, e.g., for key generation. On Linux and BSD systems, this works by
227 # reading /dev/urandom. It should be noted that the OS entropy pool needs to be
228 # properly initialized before hostapd is started. This is important especially
229 # on embedded devices that do not have a hardware random number generator and
230 # may by default start up with minimal entropy available for random number
233 # As a safety net, hostapd is by default trying to internally collect
234 # additional entropy for generating random data to mix in with the data
235 # fetched from the OS. This by itself is not considered to be very strong, but
236 # it may help in cases where the system pool is not initialized properly.
237 # However, it is very strongly recommended that the system pool is initialized
238 # with enough entropy either by using hardware assisted random number
239 # generator or by storing state over device reboots.
241 # hostapd can be configured to maintain its own entropy store over restarts to
242 # enhance random number generation. This is not perfect, but it is much more
243 # secure than using the same sequence of random numbers after every reboot.
244 # This can be enabled with -e<entropy file> command line option. The specified
245 # file needs to be readable and writable by hostapd.
247 # If the os_get_random() is known to provide strong random data (e.g., on
248 # Linux/BSD, the board in question is known to have reliable source of random
249 # data from /dev/urandom), the internal hostapd random pool can be disabled.
